One of Magnatone's preimum amplifiers of the late 1950's (the only thing bigger was the 280). The 260 is a two channel amp, each channel using a 12AX7 gain stage followed by "volume", "treble", and "bass" controls in a Baxandall arrangement. A four varistor F.M.Vibrato circuit is used (same circuit would continue on into the 1960s with the M10A.
Some small circuit changes, including the addition fo a "mellow" / "normal" switch (with was a .0047 cap to ground following the first gain stage) prompted Magna to change the model name to be 260A.
The cabinet trim and grill cloth was changed for the 260A (see pics). Estey bought Magna during the 260A production, and the screening on the control panel was changed to reflect that.
When the 400 Series was designed, reverb was added to the 260A circuit and given the model designation of 460. However, the 260A also continued as a non-reverb amp with the designation of 262. A 6EU7 preamp tube was used instead of the 260A's 12AX7. The cabinet was updated to the style used in the 400 series. These 262's were built in 1962, and maybe through the first half of 1963. They did not appear in the 1961 catalog, and might have been brought back because a non-reverb 460 model was requested by dealers or by one of the major OEM's, like Imperial or Deffner.
The 262R was released August 31, 1961 as a 262 with reverb. The circuit was a nearly a 460 with a few changes including the use of a 12AX7 instead of a 6EU7 as the first pre-amp gain stage. There was another change to the Channel 1 tone circuit that might have been a benefit to accordion players (subtle change).
